TNCC Seventh Edition study guide 2023
What roles are vital to a trauma team? - CORRECT ANSWER--The patient
-The team leader
-Core team
-Contigency and support services
What are the characteristics of an effective team? - CORRECT ANSWER-- Clear roles
and responsibilities
- Shared mental model
- Optimize resources
- Strong team leadership
- Engage in regular discipline of feedback
- Strong sense of collective trust and confidence
- Create mechanisms to cooperate and coordinate
- Manage and optimize performance outcomes
-Interdependent and adaptive
What are key foundations to successful teamwork in the care of the trauma patient? -
CORRECT ANSWER-care coordination, clear communication, and timely systematic
assessment
What tools can be used to promote communication within a team structure? What are
the benefits of each? - CORRECT ANSWER-- Brief: designed to form the team,
designate team roles and responsibilities, establish climate and goals, and engage the
team in short and long-term planning
- Huddle: ideally convened prior to trauma patient's arrival; communicate critical issues
and emerging events, anticipate outcomes and likely contingencies, assign resources,
express concerns
- Debrief: process improvement
Define trauma - CORRECT ANSWER-Injury to living tissue caused by an extrinsic
agent; creates stressors that exceed tissue or organ's ability to compensate
Define epidemiology - CORRECT ANSWER-Study of factors that determine and
influence the frequency and distribution of injury, disease, and other health-related
events and their causes in a defined human population
When is the potential for traumatic injury present? - CORRECT ANSWER-Whenever
energy comes in contact with the human body
,Define kinematics - CORRECT ANSWER-The study of energy transfer as it applies to
identifying actual or intentional injuries
Define biomechanics - CORRECT ANSWER-The general study of forces and their
effects
Define mechanism of injury - CORRECT ANSWER-How external forces are transferred
to the body, resulting in injury
Define potential energy - CORRECT ANSWER-Stored energy; "at rest"
Define kinetic energy - CORRECT ANSWER-Energy in motion
Describe Newton's First Law of Motion - CORRECT ANSWER-A body at rest will
remain at rest, and a body in motion will stay in motion unless acted upon by an outside
force (energy)
Describe Newton's Second Law of Motion - CORRECT ANSWER-(F)orce = (m)ass x
(a)cceleration; It takes more force to move a heavy object
Describe Newton's Third Law of Motion - CORRECT ANSWER-For every action, there
is an equal and opposite reaction resulting from the transfer of energy
Describe the Law of Conservation of Energy - CORRECT ANSWER-Energy can neither
be created nor destroyed, but it can change form
What are the five forms in which energy exist? - CORRECT ANSWER-- Mechanical:
direct impact of an object
- Thermal
- Chemical
- Electrical
- Radiant
The consequences of mechanical energy are directly related to __________ energy -
CORRECT ANSWER-Kinetic
Kinetic Energy (KE) is equal to - CORRECT ANSWER-1/2 the mass multiplied by the
velocity squared
In other words: when mass is doubled, energy is doubled; when velocity is doubled,
energy is quadrupled
Kinetic Energy formula - CORRECT ANSWER-KE=1/2mv^2
Differentiate between internal and external forces of energy transfer in the context or
trauma. - CORRECT ANSWER-External forces are how energy can impact the body
, (e.g., deceleration, acceleration, compression). Internal forces represent the ability of
the body to withstand external forces.
How do internal forces protect the body from injury? - CORRECT ANSWER--
Compression strength: ability of tissue to resist crush injury or force
- Tensile strength: ability to resist being pulled apart when stretched
- Shear strength: ability to resist a force applied parallel to the tissue
List four main types of traumatic injury - CORRECT ANSWER-- Blunt trauma
- Penetrating trauma
- Thermal trauma
- Blast trauma
Examples of blunt trauma - CORRECT ANSWER-Falls
MVA
Vehicle vs. pedestrian collisions
Assaults
*Can result from broad energy impacts across large surface areas and involve energy
transfer causing deceleration or acceleration
*Greater distance of transfer diminishes deleterious impacts, and the more focused the
impact, the greater the damage
Deceleration injuries - CORRECT ANSWER-Occurs as energy is dispersed from the
moving object
* The speed of an impact is often less significant than the distance over which the
energy is transferred
Differentiate between deceleration and acceleration forces. - CORRECT ANSWER-pg.
28
What environmental and pathophysiologic factors are considered when the mechanism
of injury is a fall? - CORRECT ANSWER-- Point of impact
- Type of surface that is hit
- Tissue's ability to resist
- Acceleration
When is a fall considered significant in the pediatric patient? - CORRECT ANSWER-If
the fall is from three times his or her height
Describe the three impacts in the motor vehicle impact sequence. - CORRECT
ANSWER-1. Vehicle hits another object
